Free online 25 minute timer
A 25 minute timer that shows your real focus
The classic Pomodoro length — but with a twist. Two clocks share the 25 minutes: one for focus, one for break. Tap to switch when your attention slips. At the end, you see what percent of your Pomodoro was actually focused work.
Why 25 minutes works
25 minutes is short enough that anyone can commit to it — even on a bad day, even with a hard task. It's the on-ramp to deeper work. Stack a few 25s back-to-back and you've put in two solid hours without noticing.
How TimerDuel's 25 minute timer is different
- • Two clocks, one session. Focus runs while you work, break runs when you drift. Total stays at 25.
- • No guilt mode. Got distracted? Tap break. No tree dies, no streak resets.
- • Real focus rate. At the buzzer, you get a single honest number. That number is what changes behavior.
FAQ
Why a 25-minute timer?
25 minutes is the classic Pomodoro length — short enough to commit to even on a low-energy day, long enough to make real progress. It's the easiest entry point into timed focus work.
Is this 25-minute timer free?
Yes — free, no signup, no install. Open it in any browser and start. Works on desktop, phone, and tablet.
Can I extend past 25 minutes?
Yes. TimerDuel lets you pick any length. Start with 25, then push to 45 or 90 once you've warmed up. The chess-clock still measures your real focus rate either way.
What do I do during the break?
Stand up, look out a window, get water. Avoid your phone — the dopamine spike kills the focus you just built. 5 minutes is the standard Pomodoro break.
How is this different from a normal 25-minute countdown?
A normal countdown counts elapsed time. TimerDuel runs two clocks — focus and break — so at the end of your 25 minutes you see how much was real focus vs. drift. Most people are shocked the first time.
